n Die-Cutting Machines, of which the followmg 1s a; specification, reference being had therein to the accompanying drawings.

This invention-relates to die cutting machines, and has for its object to provide a machine that will form dies or molds from -a model or attern and grade the same both larger an smaller so that the length of the work may be made in any redetermined ra-- tio to the length ofthe mo el or pattern, and

the width of the, mold may be made in any predetermined ratio to the width of the model or pattern, also that the ratio between thelengthand the width may be made independent ofeach othen In the ordinary die forming machine where .the die is'cut from a attern said die is made an exact facsimile o the mold, either larger or smaller, bit in direct proportion to the same in all directions, the cutter being controlled to act on'the die by'the movement of the pointer or tracer over the face of the pated one single bar; My improved device is more lgarticularl sinwhic direct ratioto each other, therefore the mechanism that operates the endwise movement of the work to form the length of the mold is made .and operated independent to that,

.-which operatesfthe sidewis'e movement to form the Width. I In practical operation one mold is finished of the middle. size to be usedas a pattern in they machine, and from that other molds are formedbeing graduated from the smallest 'size up as. the largest, in sizes or half. sizes as may be desired. The machinemag be 0 erated so as to graduate the width in ep tsize up to the-size of the model or p Specification of Letters iatent.

tage of making more than one width of mold from the same pattern. To accomplish this result the work and attern are mounted one above the other to he moved longitudinally by the movement of a carriage. Two arms are pivotally mounted at one end and connected together at theiropposite ends to be movedup and down simultaneously. In one arm is mountedthe cutter and in the other the tracer, and to obtain the grading of the different widths the tracer is adjusted lon itudinally either in or out in its arms to ma e its working-length"eitherlonger or shorter than the. working length of the cutter arm, thereby producing a mold either narrower or length is obtained by'regulating t e longitudinal travel of the carriage on which the work is mounted so that said travel will be This invention consists of other novel fea- .tures and rts and combinations of the same as will be l iilly described hereinafter and then pointed-out in the-a ended claims- A practical embo ent of the invention is represented in the accompanying drawings forming a artof thi's'specification, in which similar characters of reference indicatecorresponding artsin all the views.

Referring to the drawings, at 1 is the bed of-the machine that is supported on the four legs 22'. "At one end 0 this bed is mount ed both the pattern, and the work-carrying mechanism, one above the other, the mold 3 in process of manufacture bein below in the jaws 44 (see Fig. 13) whic jaws are in' turn carried on trunnions 55 in the frame 6 and may be rotated to set the mold at any desired angle to the cutter,'by ma efis s segment is'fixed'to one of'the trunnions and engaged at its periphery by the spring. lock pin 8. The pattern'9, like the work, is-

rotatably held in the jaw 10'10, and ma belocked in any desired position by the loc bolt '12 that engages the periphery of this notched segment-11. These jaws 1 0 are held ina support 13 which is inturn mounted -.to slide longitudinally on'the frame 6.

At i l-is a feed carriage on which the frame 6 is mounted. This carriage is actuated by the rack 15 and pinion 16 .bv mechanism hereinafter. described, to travel; lengthwise on the bed' and 'givethe necessary longitudinal feed motion to the work when the same is 'beingfoperated upon by the cutter. To obtain the longitudlnal grading' or'gradingfor. length of --mold I have j provided another longitudinally slidable carriage 60 (see- Flg. 13) that is connected to the main carriage .14 by the connection 61 through the-- stroke regulating arm 62 and to the, said pattern frame by the adjustable connection 66. This regulating arm is pivoted below at 63 and hinged to said carriage at 64. When it is desired to make the mold or work longer than the pattern, the cdnnecting point 65 is raised in the slot above the pivoting point 64 and when said mold is to be shorter than the model the said connecting point is dropped. below the said pivoting point, the amount of raise or drop being regulated to conform to the'desired difference in length between the mold or Work and the pattern.

This carriage 60 is also adjustable transversely by screw 17, and the pattern and work may be adjusted laterally on their carriage 14 by means of the screw 17. threaded into the-nut 18 in said carriage. I

The yoke 19 1s pivotall mounted on the bearing 20 and is provi ed with two .upwardly extending arms 38 and 39 and ivotally mounted in this yoke between sai arms are both the cutter arm 21v and the tracing arm 22 one directly above the other on the short shafts-23 and 24 respectively. These two arms are connected together at their outer ends by the' rod 25 so they may be actuated up and down in time with each other. The tra'c'er arm is slotted at 26 near its outer end and adjustably held in this slotis the tracing point 27 that comes in contact with the face of the model 9, this adjustment beingthe means for regulating the comparative width between the pattern and the work, as when the tracer is set out beyond the vertical line of :the cutter the work is formed narrower and when said pointer is set in or toward the the cutter t e work isformed wider than the pattern. On the edge of this shit is a graduated plate 28 scaled to correspond to the difiv'oting point of itsarm beyond ferenfi widths that may be desired and by aid of whichthc tracer may be readily ositioned for. any predetermined width. otata'bly 'mounted near the outer end of the cutter arm is the cutter 29 which is fixed onthe spine (11830.7

At 31 is the main driving the uprightmain shaft 32 an this cutter 29 receives its rotary motion from said main .shaft 32fthrough the gears 33 and 34*and.

through the, pulley 35 'th'at is connected to,

6 The cutter, and tracer armsare arranged to .ically at the end of each longitudinal stroke of -the work'carriage. The hand mechanism be fed vertically either by hand or automatis operated .throu h the handwheel 43 (see Fig. 9) to-rotate t e gearsj44 and 45 and updirection.

,the sliding bar 59 and are arranged to act on right screw 46. The rotation of this screw moves the nut 47 either up or down in it's guide 48 and the movement of this nut actuates the said cutter and tracer arms through the connection 49. The automatic feed for these arms is accomplished by attaching a small spur gear 50 to the upper end of this upright screw shaft 46 and rotating the same either to the right through the gear 51, or to the left by gear 52 and intermediate gear 53. (See Figs. 7 and 8). which either of these gears may be meshed, and the ratchet gear 55 are both mounted on the pin 56 and connected together to be acted upon-by the pawls 57 and 58 to actuate said ratchet at each end of the stroke of said work carriage and rotate the same always in one Both the said pawls are hung'in the ratchet gear alternately first one and thenthe other as said bar is moved longitudinally forward and back by the carriage 60. The carriage engages and moves said bar at the, end of each stroke by engagement of the lug 67 with the dogs 68 and 69. As above stated, when it. is desired to reverse the direc tion of rotation of the screw 46, the gear 51 is thrown out of mesh with gear 54, and gear 52 is thrown into mesh by the movement of the plate 70. Said plate 70 is operated by handlei71, and .said screw shaft 46 is driven in the reverse direction through said intermediate gear 53.

The work carriage may be operated to receive its longitudinal motion either automatically or by hand. To operate the same automatically any desired mechanism may be employed but in this case I preferably drive the shaft 77 through the worm and worm wheel 76, said worm being fixed to the shaft 79. This shaft 79 is hung in the pivoted bearing 80 at one end and held up at its'opposite end by the vertically movable bracket 81. This bracket is locked in the up position by the slide bolt 74 that engages the notch 87 therein. Loosely mounted on this shaft 79 are the two pulleys 82 and 83 that are driven each in opposite directions through the straight and cross belts 84 and 5 85 from the shaft 86 (see Fig; 1), which shaft -is driven from the main shaft 32 through the wormSS, gear 89 and cone pulleys 90 and 91. In order that the movement of the carriage may be reversed at each end of its stroke an Y (see Fig. 6).

auxiliary reversing slide plate 93 has been provided which plate is actuated at each end of the stroke of the work carriage by engagement with the adjustable dogs 94 and 95, On this slide plate is mounted the clutch lever actuating spring pin 92 which pin is arranged to be forced over the bevele leiid of the clutch lever 96 and by the tension of said pin forcing down on the bev vied portion of the o posite side of said lever, withdraw the doul) c faced friction cone 97 The large gear 54, into In case this s ring is not sufficient to accomplish the i t irowing of this clutch the auxiliary lever 98 is pivoted to the frame at 99 (see Fig. 5), and is engaged at its lower end by the pins 100 and 101 adjustably held in said slide plate 93 to engage the upper end of saidreversing lever through the pin 102 and positive] throw the friction cone into the op osite pul ey, and the carriage then moves in t 1e opposite direction until again reversed by the engagement of the dog 94 with said actuating mechanism.

When it is desired to operate the 'carriage by hand the worm 75 may be thrown out of engagement with the worm gear 76 by withdrawing the bolt or latch 74 from the notch 87 in the bracket 81 through the upward movement of the lever 73 and allow the shaft 7 9 to drop. Then the shaft 77, on which the pinion 16 is mounted, is free to be turned by the hand wheel 78 (seeFig. 5) mounted on the outer end thereof and the carriage that carries both the model and the mold may be moved longitudinally at will. a

The advantages and operation of 111 improved die cutting machine will be readi y apparent to those skilled in the'art towhich it appertains. It will'be particularly observed that I have produced a machine by means of which a die or mold may becut which will be an exact duplicate of the pattern, orwhich may vary in size in proportion to the pattern in a fixed ratio, or which may vary from the relative proportions of the pattern without any fixed ratio. In other words the relative length and width of the pattern may be reproduced; or the relative length may be reproduced with a dispro ortionate width; or the relative width may e reproduced with a disproportionate length. It will be further noted that I have provided means whereby the tracer and the cutter are automatically moved at the end of each stroke of thepattern and work holding carriages; It will also be observed that I have provided pattern and work holders that are adjnstably mounted in 5 their supporting frames or carriages.
